EnergyStar to Adopt Full Shielding Criteria for Outdoor LED Products (08 October, 2009)
A report released by the U.S. Department of Energy specified that LED exterior lighting fixtures must emit no light above 90 degrees to receive EnergyStar certification. Adoption of criteria that limits uplight for the growing field of LED fixtures will significantly reduce sky glow and curtail energy waste.
All wall mount, pole top and pole mounted outdoor LED fixtures wishing to earn an EnergyStar designation must adhere to this criteria. When asked specifically about nostalgia and antique luminaires, Jason Tuenge of the Pacific Northwest National Laboratory affirmed that the fully shielded design applies to them as well, and that “acorn” type products could not be certified if any light were emitted above 90 degrees.
This proposal will go under final review, receiving official declaration in 4 to 6 weeks, according to Richard Karney, director of the program for the DOE. If the proposal becomes law, this timely action on LED design is a powerful victory for dark sky preservation and restoration. See Department of Energy presentation >>

Regione Veneto in Italy approves a law promoting no upward-directed light! (17 August)
The introduction of this new law in a region where there was already a less effective law is of paramount importance, because politicians understood that the way to prevent light pollution evolved in the years since the old law’s approval. What seemed a small upward light percentage (3%) then, is now clear that it produces far more pollution than strictly necessary. Read more >>

These autonomous, solar-powered devices automatically record sky glow levels at regular intervals throughout the night. Read press release >>
American Medical Association Officially Supports Reduction of Light Pollution (16 June)
The American Medical Association officially supports of energy efficient outdoor lighting technology into official AMA policy by unanimously adopting the following resolutions:
RESOLVED That our AMA advocate that all future outdoor lighting be of energy efficient designs to reduce waste of energy and production of greenhouse gasses that result from this wasted energy use, and be it further
RESOLVED That our AMA develop and enact a policy that supports light pollution reduction efforts and glare reduction efforts at both the national and state levels; and be it further
RESOLVED That our AMA support that all future streetlights will be of a fully shielded design or similar non-glare design to improve the safety of our roadways for all, but especially vision impaired and older drivers.

This resolution is a monumental step toward IDA's goals of a natural sky.

IDA Releases Draft Version of Model Lighting Ordinance with the Illuminating Engineering Society (09 February)
The breakthroughs of the MLO include:
- A single ordinance that can be used in every community with little or no community-specific language through the use of five (5) Lighting Zones of differing stringencies that tailor the MLO to address local needs and preferences
- A prescriptive system for regulating most common lighting installations using a new rating system called BUG (Backlight-Uplight-Glare) that prevents excessive lighting and permits easy plan review and field inspection: Read the BUG system here.
- A computer analysis option for complex lighting installations applies the latest research findings with respect to glare, skyglow, and light trespass and restricts designs to appropriate limits of off-site impact
The MLO was open to review and public comment through 20 April, 2009. Comments have been collected and the MLO draft is under revision. Details available as they occur. Learn more >>
